Frequently Asked Questions

What is the communication protocol used by the FST100-2003 illuminance transmitter?

The transmitter uses a standard RS485 serial interface, typically communicating via the Modbus RTU protocol. This allows for reliable, long-distance data transmission and easy integration into industrial PLCs, SCADA systems, and building automation networks that support Modbus communication.

What is the required power supply for this sensor, and can it be powered directly from an Arduino?

The sensor requires a 10-30V DC power supply. It cannot be powered directly from an Arduino's 5V or 3.3V pins. You will need an external DC power source (like a 12V or 24V adapter) and must interface the RS485 lines through a dedicated RS485-to-TTL/UART converter module compatible with your microcontroller's logic voltage.

How do I install and calibrate the FST100-2003 sensor?

Installation involves wall-mounting the sensor housing in the desired location using the provided mounting points. Connect the 1-meter lead wires to your RS485 bus (A/B lines) and power supply. The sensor is typically pre-calibrated. For precise applications, calibration factors can be adjusted via Modbus commands as per the manufacturer's datasheet, referencing a certified lux meter.

Is this sensor suitable for outdoor use?

Yes, the FST100-2003 is designed for both indoor and outdoor use. Its moisture-resistant housing and wide operating temperature range (-40°C to 80°C) make it suitable for exposed environmental monitoring applications, such as on weather stations or building exteriors for daylight harvesting control.
